Probably Helical has just been accepted into Project: Encore, a database of choral compositions that have been premiered by professional choruses and have been endorsed by a panel of internationally known conductors. You can search the database here by composer, language, voicing, or tag word. The most common tags are love, nature, and peace, though songs about death outnumber those about birth by 4:1 (not counting a requiem). Most tags have only one composition, with headings such as locomotive, insomnia, and hermetic (unfortunately, not the same piece). I’ve inaugurated a DNA category.
